Transmitter architectures designed to accommodate both constant and non-constant of envelope modulation schemes and capable of providing local oscillator carrier frequencies within any one of numerous desired frequency bands, thus allowing compliance with many different communication standards. One example of a programmable frequency synthesizer includes a plurality of transmitter components and a microcontroller coupled to the frequency synthesizer and to the plurality of transmitter components. The microcontroller is adapted to provide a frequency control signal to the frequency synthesizer to control a frequency of the local oscillator carrier frequency. In addition, the microcontroller is also adapted to provide digital control signals to at least some of the plurality of transmitter components to turn on and off different ones of the plurality of transmitter components based on an operating mode of the transmitter, such that the transmitter can accommodate both constant envelope modulation and non-constant envelope modulation schemes.

A frequency synthesizer capable of high speed, low power, wideband operation including a method of gain compensation, and a method of fast voltage controlled oscillator (VCO) band calibration. In addition, the frequency synthesizer may include two or more switchable independent loop filters to facilitate wideband operation. Such a frequency synthesizer may be used in many applications, and in one example, may be particularly suitable for use in a multi-band, multi-standard transmitter or radio transceiver.

331117FE, 331177 V

A method of linearizing a frequency versus tuning voltage response of a voltage controlled oscillator comprising multiple varactor sets. In one example, a the method of linearizing includes acts of providing a first varactor set with a first bias voltage, providing a second varactor set with a second bias voltage, and adjusting the first and second bias voltages so as to linearize the frequency versus tuning voltage response of the voltage controlled oscillator over a selected operating frequency range of the voltage controlled oscillator. The method can be extended to N varactor sets and can be applied to many RF CMOS or analog CMOS components, including voltage controlled oscillators.

A reconfigurable system is used for amplifying, filtering, and sampling analog signals. Unlike conventional analog filters and amplifiers based on linear time-invariant systems and classical filter responses such as Butterworth or Chebyshev filters, the system described here uses parallel branches comprising time-varying circuits. An input voltage or current is communicated to a number of parallel branches and each branch processes a segment of the input signal using time-varying circuits such as analog multipliers and/or super-regenerative amplifiers. The time-window of the input signal processed by each branch is equal in length, but offset in time from all other branches. The output of each branch is a series of filtered and amplified samples of the input signal. The output samples of all branches are then time-interleaved in the analog domain, or digitized using separate analog-to-digital converters and then time-interleaved digitally. By using time-varying circuits, sharper filters and greater amplification is achieved while consuming less integrated-circuit area and power. The time-varying circuits in each branch are controlled by synthesized signals that determine the filter response and gain of the overall system. As a result, better flexibility and reconfigurability are achieved compared with classical filters and amplifiers.
